As shown in the example above, you may create your own video sitemap as per your website's requirements. After your video sitemap gets created, you may submit it to Google via Webmasters Tools.

Note: Limitation of video sitemaps are 50000 entries per sitemap. If you have more videos then it is recommended to create more than one sitemap and specify each of the separate sitemaps on one index sitemap.
